I have a "winchbit.com" version. I just bought a second one, just in case the original one goes
overboard. My original has fallen out a few tmes, fortunately the cat has large flat decks. I have a very large (800sq.ft.) main and it makes easy
work of raising it and most of all fast
work. I originally used the Milwaukee 18volt cordless right angle drill, but this year have upgraded to the 28 volt model, YEAH MORE POWER!!! and last longer. With the winch bit and drill my wife can raise the main. It also makes quick work on the
roller furler.
